Abstract: A magnetic field sensor element comprises an elongated core of high-magnetic permeability material having a coil of electrically-conductive wire wound around and along a central axis of the core. The sensor, due to inductance of the core which changes with application of a local magnetic field, exhibits a characteristic of delaying an electrical input as a function of the strength of a magnetic field in the direction of the axis of the core, and the delay is measured as a function of the strength of the magnetic field. Appropriate circuitry provides at least one step-function voltage input to the coil such that the resulting delay in current charge-up into the coil creates a voltage across the coil which decays to a known reference value. The time delay for the voltage decaying to the reference value varies as a monotonic function with the strength of the applied magnetic field to be measured.

Abstract: A telephony call-waiting system for clients having a computer with a video display unit (PCNDU) and a public-switched telephony network (PSTN) telephone connected to the PSTN by a single line, keeps a status indication of the client's Internet connection status and, during periods of time the PC/VDU is connected to the Internet, alerts the client by an alert signal over the Internet connection of any waiting PSTN calls. In a preferred embodiment the client's PC/VDU is adapted to provide an audio and/or visual alert event when an alert signal is received, and to provide for a user-initiated response to an alert, accepting or rejecting a call.

Abstract: A method for creating and disseminating knowledge-based object models converts object models created on a source platform to a first human-readable flat file prior to transmission on a network, allowing object models to be transported across differing platforms incorporating different languages. At a network receiving station, a transmitted flat file is read and the object model is recreated by a run-time engine. In some embodiments flat files created on the source platform are used by a graphical user interface (GUI) model builder to create a GUI object model associated with the first object model, which is converted to a second flat file to be transported to a receiving station along with the first flat file. Both flat files in this embodiment are used at the receiving station to recreate the associated object models. In further embodiments multimedia files are generated on the source platform and associated with the GUI object model, and transported to the receiving station along with the flat files.

Abstract: A communication router receives incoming communications and assigns a priority to each, which are then placed in a routing queue in descending order of priority from the head of the queue, to be routed from the head of the queue to selected destinations. The invention is particularly applicable to routing telephone calls in a call center. Destinations, in the call center agent stations arc selected on a basis of agent availability, and an agent status may be available if the agent is involved in a call of lower priority than a call to be routed. In some embodiments displaced calls may be placed back in the routing queue in order of priority. The invention is applicable to routing a wide variety of communications, such a telephone calls, e-mails, video calls, and Internet Protocol calls.

Abstract: A call queueing system for a call center establishes virtual calls for callers, and allows the callers to disconnect and await a later callback when the virtual call is routed to an agent. Callers are connected to an IVR and informed that they may disconnect and await the callback. An IVR may also be used when the callback is made, informing the caller of the nature of the new call, and that they are now being connected to an agent. In some instances virtual calls may be sequenced in the same queue with real calls. The virtual call system may be initiated in a call center by exceeding load threshold, at particular time frames, and the like. A key is associated with each virtual call in a manner that the origination number of the call for whom the virtual call is entered may be retrieved when the call is routed to an agent. The system is adapted to work with all intelligent routing systems.
